There has been a many studies about soil nailing method to low-strength embankments that were neighboring important infrastructures such as railways and highways, in consideration of intensified disaster recently. These embankments has many constraint conditions, such as work period reduction, foreshortening reinforcement body. For these reasons, we undertaken development of efficient earth reinforcement that have solution to these problems using expanded reinforcement body by pressure injection. In this paper, the result of verifying the effectiveness this method will be state.
